AUTOMATHC CUT-OFF.

SPEIFIGATION forming part of Letters Patent No. 579,464, dated March 23,1897. Application tiled March 18, 1896. Serial No. 583,846. (No model.)

To all whom t may concern.-

Be it known that I, CHARLEs E. BENTLEY, a citizen of the United States,residing at the city of New York, county and State of New York, haveinvented a new and Improved Automatic Cut-Off, of which the following isa specification.

rlhis invention has for its main object to prevent damaging overiiows ofwater from service-pipes caused, for instance, by leaving a faucet openor by gnawing of the pipes by rats or mice or by accidental bursting ofthe pipes.

In its preferred and most complete embodiment the invention comprises awater or fluid motor, preferably in the form of a meter, measuring thefluid passing through a service-pipe having a valve, preferably aself-closing valve, and controlling mechanism automatically closing thepipe-valve and actuated by pressure of fluid passing the valve and alsoby the motor or meter mechanism, and whereby the valve will beautomatically closed when any predetermined quantity of water or othersubstance has uninterruptedly passed through the meter and valve. Thehand -operated Valve-opening devices are so made that they cannot betampered with to prevent automatic closure of the valve by the mechanismat proper time.

The invention further comprises various novel constructions,combinations, and subcombinations of parts of the cut-off' mechanismalone and as combined 'with the motor or meter apparatus, all ashereinafter described and claimed.

Reference is made to the accompanying drawings, forming part of thisspecification, and in which similar numerals indicate like parts in theseveral views.

Figure l is a sectional side elevation of the combined meter and cut-offmechanism. Fig. 2 is a plan view thereof, with parts in horizontalsection on the line @one in Fig.V l. Fig. 3 is a central verticalsectional view taken on the line y y in Fig. 4 and showing otheradjustments of the parts. Fig. 3c is a detail view of the stop-wheel andpulley pawl devices, more clearly showing different adjustments of theparts. Fig. 4 is a central vertical sectional view of parts shown inFig. 3, the section being taken on the line .a in said figure. Figs. l,lb, 3a, and 31 are detail sectional views of the service-pipe valve atdifferent adjustments hereinafter explained, and Fig. 5 is a detailvertical sectional front view sufficiently illustrating a modification.

In the following specification I will for greater convenience refer tothe fl uid-motor as a meter, but it will be understood that any motorapparatus operated by water or fluid flowing through the service-pipemaybe employed, and that in so far as concerns certain features of thecutoff mechanism hereinafter claimed any motor actuated by independentclockworks or other mechanism may be used within the scope of theinvention.

The water or iiuid meter l may have any approved construction as regardsits internal measuring devices and its registering meehanism. In thepreferred construction (shown in Figs. l to 4, inclusive, of thedrawings) the several counter-disks of the meter registering mechanismare arranged as usual upon a horizontal shaft 2, rotated from a verticalshaft 3, actuated by the Huid-measuring devices within the meter. Theshaft 3 carries a worm 4, engaging a toothed wheel 5, fast on a shaft 6,which carries a pinion 7, engaging a gear-wheel 8 on the counter-shaft2, which at its opposite end carries a pinion 9.. The pinion 9 isadapted to rotate a gear-wheel l0, fast on a shaft l1,journaled in theouter ends of a forked lever l2, which is fulcrumed loosely upon a shaft13, adapted to be rocked by pressure of water in the service-pipe, aspresently explained. On the shaft ll is also fixed a gage-wheel 14,which thus rotates with the gear l0. A spring l5, held at one end to theshaft 1l and at the other end to the lever l2, returns the gage-wheel toinitial position. rlhis position of rotation is controlled by thespecial adjustment of an elastic stop-arm 1G, which is loose on theshaft ll and carries a stud 17, adapted to any one of a series of holes17n in the gage-wheel. lVhen the gagewheel is retracted by the springl,the stop 1G strikes a shoulder at the inner part of the leverI l2. Thegage-wheel is peripherally recessed to provide a radial shoulder and atangential shoulder 1 8. To a plate iiXed to the inner face of the wheelis pivoted a pawl 19, the inner end of which stands oft' from the radialshoulder sufciently to form a radial IOS) notch 20, and also stands offfrom the tan gential shoulder 18 for a distance exceeding the diameterof a pin 21 on one end of a twoarmed trip-lever 22. The point of thepawl 19 finishes about even with the circumference of the gage-wheel, tothe curve of which the back of the pawl preferably conforms. A spring 23normally holds the pawlpoint close to the body of the gage-wheel, butallows the pawl to swing open about parallel with the wheel-shoulder 18to permit outward escape of the trip-lever pin 21 after it has enteredthe wheel-notch 20, as hereinafter more fully explained.

The trip-lever 22 is hung loosely upon the shaft 13, and its upper armmay be weighted, but is preferably connected by a spring 24 with onelimb of the forked lever 12 in order to throw the other pendent arm ofthe trip-lever forcibly against a pin 25, projecting` from a pawl-detent26, the opposite end of which engages a notch in a stop-wheel 27, whichis loose on the stem of the valve 28 of the service-pipe 29. When thepawl 26 is tripped from wheel 27 by lever 22, the valve 28 is preferablyclosed automatically, as hereinafter described. To the shaft 13, onwhich the gage-lever 12 and trip-lever 22 are loosely hung, is fixed arocker-arm 30, which has a pin 31 projecting outward beneath the innerpart of the lever 12. A spring 32, held to the top of the rocker,readjusts the lever 12 and its gage-wheel 14 to normal raised positionsafter flow of water through the apparatus is cut off.

In the service-pipe 29 is interposed beyond the valve 28 a casing 33,accommodating within it a lever-arm 34, fixed to the rocking shaft 13,which projects through a stuffing-box of the casing to receive the parts12 22 30 above mentioned. The free end of lever 34 has a pin-andslotconnection with a piston 35, adapted to a chamber of the casing, whichcommunicates with the valve 28. The piston is guided by passage of itsrod through a bearing 36. An additional guide 37, fixed to the piston,may also be used if desired.

To the stem 38 of the valve 28 is fixed a ratchet-wheel 39, preferablyhaving but four equidistant peripheral notches or shoulders 40, adaptedfor successive engagement by two pawls, one pawl 41 being pivoted to theabovenamed stop-wheel 27. This wheel 27 carries a fixedlaterally-projecting pin or stud 42 and also preferably has a peripheralstud 43, adapted to engage a fixed stop 44 to limit backward turning ofthe wheel to about onequarter of a revolution. The stop-wheel preferablyhas two peripheral notches 45 46, separated for about one-quarter of itscircumference and adapted to receive the abovenamed pawl 26.

At the opposite face of the ratchet-wheel 39 is placed loosely on thevalve-stem 38 a pulley 47, to which is fixed an operating-cord 48,extending upward through a casing 49, inclosing the gage and trip-leverand valve mechanisms to prevent tampering with them. The casing is shownwith a hinged and glazed lid 50, permitting reading of the counter-disksor dial through the glass. A lock 51 is preferably provided for thelid.The cord-pulley 47 carries two peripheral studs 52 53, adapted to afixed stop 54 to limit rotation of the pulley to about one-quarter turnin opposite directions,and a spring 55 retracts the pulleyto normalposition with its stud 52 against stop 54. At its inner face the pulley47 carries two pawls 56 57 and a pin 59. The spring-pressed pawl 56engages one of the'notches 40 of the valvestem ratchet-wheel 39, whilethe gravitating pawl 57, having an angular finger 58, acts in connectionwith the pin 59 and the pin 42 of the stop-wheel 27 to turn the latterthrough the medium of pulley 47 when the cord 48 is pulled. A spring 60returns the stop-wheel 27 to normal position.

I prefer so to construct the valve 28 that it may serve also as a meansfor draining off the water left in the service-pipe 29 when thesupply-passage of the valve is closed, thereby preventing freezing ofthe pipes or mechanism at any point beyond the valve. I thereforeprovide the valve body or plug with a main straightway passage 61,adapted to register with the passage 62 of the valvecasing. I also formthe valve-plu g with two transverse drainage-passages 63 G4, adaptedupon successive half-turns of the valve to al ternately connectthedrainage-passages 65 and 66 in the valve-casing. The passage 65 opensto the passage 62 beyond the valve-plug, and the passage 66 opens to adrip-pipe 67, leading to any safe place of discharge. This self-drainingfeature of the valve is not new of itself, but is specially useful incombination with a pressure-operated means such as the piston 35 and thegage and tripping devices of the automatic cut-off.

The operation is as follows: After the valve 28 has last beenautomatically closed, the parts assume relative positions shown in Figs.1, 2, 1, and 1b of the drawings. The valvepassages 65 63 66 are now incommunication and the water in the service-pipe is draining therefromthrough the drip-pipe 67. To open the main supply-passage 61 of thevalve, the cord 48 is pulled and then released with the followingresults: As the cord is pulled the pulley 47 is turned in direction ofarrow a in Fig. 1 until the pulley-stud 53 strikes the stop 54. Shortlyafter the pulley begins to turn, the finger 58 of its pawl 57 strikesthe pin 42 of the stop-wheel 27, and as the pawl 57 is now held againstturning independently on its pivot by the pulley-pin 59 the pawlfinger58 carries the pin 42, and consequently the stop-wheel 27 around withthe cord-pul ley 47. As the pulley about finishes its quan ter-turn thepulley-pawl 56 drops into or is ready to enter the next rearward notch40 of the valve-stein ratchet 39, (see the dotted position of this pawlin Fig. 3,) and the pawl 26 also enters the notch 46 of the stop-wheelIOO IIO

27. The valve 28 is yet closed and will not be opened until after thepulled cord 48 is released. When the cord 48 is released, the spring atonce retracts or turns back the pulley 47 ,Y and the pulley-pawl 56having already7 engaged the next rearward notch 40 of ratchet 39 it isobvious that as the pulley is retracted by spring 55 until its stud 52again strikes the stop 54 the pawl 5.6 will be carried around aone-quarter turn in direction of arrow b in Figs. 3 and 1 of thedrawings, thereby also carrying the valve 28 around to the positionshown in Fig. 3au and opening the valve supply-passage 61 to theservice-pipe 29, and at the same time closing the outlet to thedrainage-pipe 67, the closed drainage port or passage 64 thencommunicating withthe 4valve-case passage 65, as shown in Fig. 3b.

As the valve is thus being turned to open position by theretractingpulley the pawl 26 in the notch 46 of stop-wheel 27 preventsretraction of said wheel by its spring and the pawl 41 of wheel 27engages the next rear Ward notch 40 of the valve-stein ratchet 39, readyto give this ratchet and the valve rigidly connected with it anotherquarter-turn in the same direction to automatically close the valveafter the pawl 26 is tripped automatically by the cutoff devices, aspresently explained. Thile the valve 28 remains open after release ofcord-48 the stop-wheel 27, its pawl 41 and pin 42, the detent-pawl 26and ratchet 39, and the cord-pulley pawls 56 57 and pi n 42 retainrelative positions shown in full lines in Fig. 3 of the drawings.

When flow of water (or other iiuid) through the meter 1 and along pipe29 is permitted by an open faucet or by cutting or bursting oftheservice-pipe at any place beyond the cutoff devices, water circulationis established through the meter and service-pipe. This circulationexerts pressure on the piston 35 and forces it forward, as shown in Fig.3, thereby permitting flow at c past the piston to the place ofdischarge. As the piston is thus advanced by iiuid-pressure it rocks thelever 34, the shaft 13, and the arm 30, therebyv lowering the arm-pin 31and permitting' lever 12 and gage-wheel 14 to fall by gravity until thegage gear-wheel 10 engages the now rota-ting pinion 9 on the shaft 2 ofthe meter counter mechanism. As the levers l2 22 both are loose on therocker-arm shaft 13, said levers fall with the gage-wheel 14, while thespring 24 draws the pin 21 of trip-lever 22 against the periphery of thegage-wheel, which wheel with its stop 16 is now rotatingin direction ofar row (l in Figs. 1 and 3, as its driving-pinion 9 is rotated indirection of arrow e by the counter mechanism. This slow rotation of thegage-wheel continues until the trip-lever pin 21 rides over thegage-wheel pawl 19 and enters the wheel-notch 20,wherein it is quicklydrawn by the spring 24, which thus rocks the lever 22 independently onthe shaft 13 and throws the pendent arm of the lever 22 forcibly againstthe pin 25 -of detent -pawl 26,

thereby positively tripping the latter from notch 46A of stop-wheel 27,whereupon the spring 60 instantly returns the stop-wheel to initialposition with its stud 43 against the stop 44, and the pawl 26 entersthe stop-wheel notch 45 merely to prevent overstrain of the pawlspring.During retraction of the stopwheel 27 its pawl 4l gives a onequarterturn to ratchet 39 and valve 28, thus again closing the valve, as shownin Fig. 1a, and simultaneously connecting the valve-passage 64 withpassages 66 to drain on? the water from the serviee-pipe system throughthe drip-pipe |67. Immediately the valve 28 is thus automatically closedthe water circulation ceases and the meter-pinion 9 and trip gage-wheel14 stop rotating, and the spring 32 now pulls the rocker-arm 30 back toinitial position, thereby causing the ar1n-pin 31 to lift or swing thelever 12 and carryinggear-wheel 10 away from the pinion 9, whereupon thespring 15 at once returns the gage-wheel to initial position, when itsstop 16 strikes the lever 12, as shown in Fig. 1 of the drawings. Duringthis return movement the pin 2l of trip-lever 22 swings the pawl 19 openas the pin escapes along the gage-wheel shoulder 18 to the periphery ofsaid wheel. As the spring 32 retracts the rocker-arm 30 the piston 35 isreadjusted, as shown in Fig. 1, and water remaining inthe pipe 29 andcasing 33 escapes around the pistonwperiphery, which loosely fits withinits final resting-place in the casing. The valve 28 will remain closedand the automatic cut-off mechanism remains inoperative but ready forthe next pull and release of the cord 48 to open the valve as abovedescribed.

The distance the gageewheel 14 turns before the trip-lever pin 21 entersthe wheelnotch 2O will determine the time the valve 28 remains open.Hence by adjusting the gagewheel stop 16 to have its pin 17 enter adifferent hole 17 in the wheel the retractingstop 16 will strike thelever 12 sooner or later, accordingly as it is desired to allow a lesseror greater volume of water to pass uninterruptedly through the openvalve 28 into the servicepipe 29 before the valve is automaticallyclosed. Any smaller volume of water than that passing uninterruptedlythrough the open valve 28 prior to entrance of the trip-lever pin 21into the gage-wheel notch 2O will not cause closure of the valve. Henceany ordinary quantity of water may be drawn from faucets any number oftimes for cleaning or household purposes without danger of prematurelyclosing the valve. After drawing such lesser volume of water the spring32 will readj ust the piston 35l and raise the rocking arm 30 and causethe arm-pin 31 to again lift the gage-wheel gear 10 from themeter-pinion 9, and the spring 15 will then retract the gage-wheel untilthe stop 16 strikes the lever 12, as above described. The piston 35 maybe moved forward varying distances by varying pressures of iuid in thepipe 29 on the piston 35 without in j uriously affecting IOC IOS

TIO

the cut-off mechanism, this being illustrated in Fig. 3, wherein thepiston is advanced farther than necessary to allow the gear 10 to engagepinion 9. In this case the rockerarm 30 moves farther than necessary andits pin 31 drops from lever 12, which is stopped by engagement of thegearing 10 9.

It is most desirable that the pull-cord 48 and the incased pulley andstop-wheelmechanism connecting it with the valve 28 should be soarranged that it will be impossible for any one by manipulating the cordfrom outside the casing 49 to prevent automatic closure of' the valve bythe trip mechanism. It is also desirable that the cord may be operatedto permit intentional closing of the valve at any time. The pulley andstop-wheel mechanism shown and above described is specially designed toaccomplish these results in manner next explained.

Suppose the cord 48 had been pulled and released and the valve 28 is nowopen and the pulley-pawls 56 58 and stop 59 occupy positions relativelyto the stop-wheel 27 andits pawl 41 and piu 42 shown in full lines inFig. 3 of the drawings. If now a malicious person should pull the cord48 and then hold or fasten it up to prevent retraction of the pulley byits sprin g 55, thereby supposing that this would prevent automaticclosure of the valve 28, it is obvious that the pawl 57, as the cord waspulled, would not strike the pin 42 of stop-wheel 27, as this pin nowhas the lowerinost position shown in Fig. 3. Hence as the pulley 47 wasbeing turned onequarter around by pulling the cord the pawl 57 wouldhang plumb and finally take the vertical dotted position shown in Fig. 3and full-line position shown in Fig. 3. Should the pawl 26 now betripped from stop-wheel 27, the pawl 57 would allow the stop-wheel pin42 to pass it as said wheel was retracted by its spring 60. Hence thevalve 28 would without fail be closed as the stop-wheel was retracted.Vhen the fastened-up cord later is released, the spring 55 retracts thecordpulley 47, and toward the end of this movement the finger 58 of pawl57 strikes the pin 42, now in the dotted position shown in Fig. 1, andpasses the pin, and all parts now are readjusted relatively as shown inFig. 1, ready for the next pull and release7 of the cord for againopening the valve.

To intentionally close the open valve 28 by means of the cord 48, atnight, for instance, it is only necessary to pull and release the cord.In this case the pawl 57 would hang plumb and pass by the stop-wheel pin42 and the pulley-pawl 56 vwould engage the next lower notch 40 ofratchet 39, as shown in Fig. 3C, and when the cord is released the pawl56 turns the ratchet and the open valve 28 one-quarter around and closesthe valve. To open the valve again, say in the morning, it is onlynecessary to again pull and release the cord 48, which causes pawl 56 togive the closed valve another quarter-turn, thereby opening it andleaving all the parts adjusted for automatic closure of the valve whenthe pawl 2G is next tripped from stop-wheel 27 in manner hereinbeforedescribed.

Various modied forms of mechanism may be used within the scope orprinciples of operation of the invention. One modification (shown inFig. 5 of the drawings) is briefiy described as follows:

A horizontally-m ovin g piston 68 in a casing 69, interposed inservice-pipe 29, rocks a twoarmed lever 70, supporting ahorizontallyrevoluble gage-wheel 71, having a flange 72, provided with anotch 73, and also having a retracting-spring 74. The lever 70 iscoupled by a rod with a rocking guide 76, having a pin 77, entering aslot of the rod, which has a spring 78 normally expanding against thepin. The guide 76 has a pin 79, adapted to bear on gage-wheel fian ge 72, and also carries a loose ball-hammer 80. In operation thewater-pressure forces piston 68 forward, thereby rocking lever 7 O andswinging gage wheel 7l against a rotating gear 8l of theregisteringtrain of a water-meter 1a of different style from that shownin Figs. 1 and 2 of the drawings. Simultaneously the rod 75 tilts guide76 and carries its pin 79 down upon the gagewheel flange 72. When theindex-gear 81 turns the gage-wheel 71 sufficiently to bring its notch 73under guide-pin 79, the spring 78 gives a final tilting movement to theguide, which suffices to throw its ball-hammer 8O forcibly down upon thetail of pawl-detent 26a and release it from the stop-wheel, therebypermitting the valve 28 to close automatically. Vhen circulation stops,a suitable spring 7 Oat retracts lever 7 0, gage-wheel 71, and piston 68and readjusts the tilting trip 76 8O to initial full-line posit-ion andthe spring 74 retracts the gage-wheel rotatively. In this modificationthe piston 35 (or equivalent means operated by fluid-pressure) firstautomatically throws the gage device into operative relation withdriving mechanism of the meter or motor, and this meter mechanism thenactuates the gage device to control the time at which it shall permitclosing of the valve, substantially as with the preferred constructionfirst described. By adjusting the gage-wheel 71 to carry its notch 7 3to position allowing a less or greater rotative movement of the wheelbefore the notch is presented to the tripper-pin 79 a lesser or greatervolume of water will uninterruptedly pass into the service-pipe beforethe pawl 26a is tripped to allow the valve 28 to close. The stop-wheeland cord-pulley with their pawls are arranged for operation with thevalve 28 in manner hereinbefore described.

Other modifications may be made within the scope of the combinations andsubcombinations specified in the appended claims, as, for instance,- thegage device instead of being revoluble may be a straight or curvedreciprocating bar having a notched flange moving along thc trip-pinuntil the pin enters the Iii notch and permits tripping of the valve-detent, and weights may be used instead of the spring retracting devices15,24, 32, 55, and 60.

Wherever in this specification the word pipe is used it includes anordinary pipe or a casing or conduit of any form through which anysubstance may iiow under control of a valve.

My invention differs in two important respects from prior inventions ofthis class known to me, and as follows: First, the valve of my apparatuscloses automatically only after a certain predetermined quantity offluid has passed uninterruptedly through it or along the pipe, and,second, the gage or fluidA measuring devices, after being automaticallythrown into operative relation with a driving mechanism of the meter ormotor by pressure of the flowing fluid, are always automatically readjusted to their original positions after being either partially ort'ullyoperated,whereby the gage devices are always ready to automatieall ymeasure the same predetermined quantity of uninterruptedlydowing iuidnecessary to assure closing of the valve.

` In an application for another patent tiled simultaneously with thisone and having Serial No. 583,847 I have described a cut-oit apparatusdiffering from the one herein shown in that the valve is automaticallyclosed by trip devices controlled by a governor operated automaticallyyby pressure of the flowing iiuid and tripping the valve-detent to permitclosing of the valve only after the lapse of la certain predeterminedperiod ot' time and without regard to the quantity of iiuid which passesthe open valve during this time.
